dmesg

Since "bf0eb89 drm/nv50-/disp: audit and version DAC_PWR method" my VGA monitor connected via DVI-I stays black after suspend/resume. The backlight is still on and can be toggled with xrandr --off/--auto, but I don't get any image. rmmod+modprobe nouveau does not help either, I need to reboot to get an image back.
Another monitor connected via DVI-D is still fine.
I can't see anything obvious in dmesg.
